If the behaviour of array functions on empty arrays is ever revised in the future, then we should keep everything consistent. So e.g. if a _future_ RFC decides to make array access throw instead of yield NULL, then this should affect array_{first,last} too IMO. However, that's not for now, that's a lot of ifs and hypothetical future development. That discussion should happen in the future elsewhere.
